Question

Which of the following conditions are most closely associated with the behaviour of ideal gases?
I. High pressure
II. High temperature
III. High number of moles of gas in the sample

• A. I only
• B. II only
• C. I and II
• D. II and III

Answer 1

The correct option is B II only

Option B is the correct answer.

A gas behaves ideally at higher temperature and lower pressure. At this condition, the potential energy because of the intermolecular forces of the gas becomes very less compared to the kinetic energy. And the size of the molecules also become very small compared to the distance between them.
